Update CD workflows to use use cross

* build: local cross compilation

With the intention of migrating gh action to native solution with cross

Supported targets: aarch-64-linux-gnu, armv7-unknown-linux-gnueabihf
Use cross build --target (target)

Note: docker base images have been updated. See related documentation:
https://github.com/cross-rs/cross/wiki/FAQ#custom-images

* build(cd): use cross for CD

Update container images along with it. Also a couple actions.

Use action-rs/cargo only for the built in support. It is the documented
gh actions way in the cross README. Manually would probably increase
times significantly.
